Title: Improvements relating to ball bearings
IPC: F16C33/60
Filed: 1921-01-26
Abstract: 180,390. Williams, E. Jan. 26, 1921. Ball bearings.-One of the bearing rings of a ball bearing is formed in two parts c. Fig. 1, situated on opposite sides of the balls b, the rings c having their adjacent faces chamfered near their outer peripheries and being retained in place by a sleeve or bush d having flanged ends and a peripheral indentation c which serves to space and adjust the rings c. The sleeve &c. d is initially flanged at one end only, and after the parts are assembled therein, the other end is flanged over to cause the rings c to bend on the balls. Adjustment is effected by forming the indentation e which bears on the chamfered faces of the rings and forces them apart to give the required freedom to the balls. In a modification. the indentation e bears on a split and contractile spacing-ring f, Fig. 3, placed between the rings c, one or both faces of the ring f being inclined and the adjacent contacting faces of the rings c being correspondingly formed. The. ring f may be of circular cross-section. The indentation e may be formed in the sleeve &c. before it is flanged or after the insertion of one of the rings c, the final adjustment being made by increasing its depth or a deep indentation may be initially formed in the sleeve. and adjustment effected by pressure on the end flanges of the sleeve.

Title: Production of hot reducing gases
IPC: C01B3/50
Filed: 1974-01-24
Abstract: 1407961 Hot reducing gases CENTRE DE RECHERCHES METALLURGIQUES-CENTRUM VOOR RESEARCH IN DE METALLURGIE 24 Jan 1974 [24 Jan 1973 14 Feb 1973] 03374/74 Heading C5E Hot reducing gases, comprising mainly CO and H 2 , for injection into a blast furnace, are produced by partial catalytic oxidation of gaseous hydrocarbons by steam in a reforming unit, removal of the water from the reducing gases by cooling, removal of the CO 2  by absorption and reheating of the reducing gases by heat-exchange with the flue gases from the heating of the reforming unit. If the heat of the flue gases is insufficient to re-heat the reducing gases for blast furnace use, additional heat is supplied by a burner which may be used to heat the reducing gases after heatexchange or which may be used to heat the flue gases before heat-exchange. Surplus heat may be used to produce steam by heat-exchange.

[Also in Group XXVIII] A method of making composite metal tubing comprises forming a metal or alloy strip 10, e.g. mild or stainless steel into a close helical winding and seam welding together the adjacent edges of succeeding turns of the winding at 11 to form an inner tubular layer and similarly forming around and upon said layer a second close helically wound and welded strip 12 of a different metal or alloy to form an outer tubular layer in contact with the inner layer. Finally, the tube is given a single cold pass in a rolling mill to pressure weld the contacting faces of the layers 10, 12 together. Additional layers of the same or different metals may be added and wound in the same or opposite directions. The strip may be wound under tension and the outside diameter of the inner welded layer and the strip metal for the outer layer slot blasted or pickled.

Perforating and dividing by fusion. -In a blowpipe machine for cutting metals of the type in which the movements of the blowpipe are controlled by mechanism connected to a wheel &c. moved over a drawing, templet &c. the blowpipe is connected to a movable device adjacent the wheel &c. so as to direct the position of the blowpipe in order to effect a straight circular, or angular cut of bevel form. The tracer 4 may co-operate with a drawing, template &c. on a table c at the side of or as shown, above the inclined blowpipe 19. The tracer 4 and blowpipe 19 are respectively carried by the members 1, 2 of a bifurcated arm which is pivoted to a turntable bracket e. The tracer wheel may be rotated by gearing 6 from an electric motor 5 and is mounted in bearings rigid with a toothed wheel 7 and hand grip 3. The wheel 7 is connected by a flexible shaft or by gearing 8 .. 16 with a toothed wheel 17 meshing with a toothed ring 20<a> on a sleeve 20 carrying the blowpipe so that rotation of the hand grip communicates a similar rotation to the sleeve 20 and. so directs the position of the blowpipes. The blowpipe is supported by a flange 19<a> and turnably mounted in one of a number of exchangeable holders 18 for holding the blowpipe at different angles, which may be vertically adjustable in the sleeve 20 by a rack and worm or pinion 21. The tracer wheel may be directed mechanically instead of by hand by using a radius bar for circular openings or by using a magnetic wheel carrier co-operating with an iron or steel templet. The wheel may be replaced by a pointer eccentrically mounted on the carrier and supported by a horizontal roller or by a vertical eccentrically mounted roller directed by hand or magnetized to engage a templet. The blowpipe and tracer may be mounted so as to obtain a cut of different size from the pattern. Specification 226,846 is referred to.

[Class 89 (i)] [Also in Group XXII] Wall plugs are made from soft and springy compacted metal fibres such as wool or swarf. The fibres may be loaded into a die around a mandrel 11 by means of a hopper extension 10 of the die and compacted between plungers 12, 14; the latter may act as an ejector. In a modification each plunger has a short pointed mandrel. The holes through the plugs may be completed by drilling or the plug may be divided transversely and held. In other modifications the plugs are formed solid and the holes are drilled, the plugs are pressed in sections 25 between plungers 23, 2.7 the sections being connected if desired by adhesives such as rubber or shellac solution. In further modifications the plugs are compacted between lateral plungers 34, 35 adjustable end plungers being also provided; any plunger may act as ejector. The end plungers may slide on a common mandrel. The plugs may be formed in part by rolling or extruding, or the metal may be partly fused together by a welding current. The exterior of the plug may have a thin coating of solder. The fibres may be of heat or corrosion resisting metals or they may be coated for these purposes. Holes may be drilled in articles made of synthetic resin to receive plugs as above to receive fixing screws. A range of sizes is made with a common external diameter but varying diameters of bore so that three or four drills will suffice to prepare holes for the complete range.

Preferred foam stabilizers are talc, mica, pyrophyllyte or a non-colloidal clay fraction, e.g. delaminated kaolinite platelets. When such stabilizers are found naturally mixed with the clay, no further addition of foam stabilizer may be necessary. Other foam stabilizers mentioned are graphite, pulverized exfoliated vermiculite and flakes of metal, e.g. aluminium and bronze. Many common foaming agents are mentioned with the combination of H 2 O 2  and MnO 2  being preferred for refractory products and H 2 O 2 /MnO 2  or acid/carbonate for building bricks. Many inert fillers are mentioned. Some resins, polymers and fibres of wood, cellulose, glass, asbestos or aluminosilicate may be added to enhance green strength. Other additives in the form of deflocculants, surfactants, and accelerators or retarders for cement setting are listed. Suitable hydraulic cements are calcium aluminates, calcium silicates, barium aluminates, Portland and slag cements.
